EDWARD W. GERRZISH, 0F LYNN, MASSACHUSETTS.

LAST.

Specification of Letters Patent.

Patented Apr. 27, 1920.

Application filed September 10, 1919. Serial No. 323,176.

To all whom it may concern:

Be it known that I, EDWARD W. GERRISH, a citizen of the United States of America, and a resident of Lynn, county of Essex, and State of Massachusetts, have invented certain new and useful Improvements in Lasts, of which the following is a specification.

This invention relates to lasts andparticularly to devices of this class known as hinged lasts and has for its object the production of a hinge connection between the heel and fore-parts which will be simple to construct, effective in operation, and inexpensive to make.

Another object "of the invention is to provide a hinge connection which may be secured to the two parts of the last without weakening the same with a number of slots and openings.

The invention consists primarily in forming semi-cylindrical depressions in the adjacent faces ofthe two parts of the last and securing in said depressions two cylinder segments, the ends of which are. positioned in rings which retain said segments together while permitting; one to oscillate relatively to the other.

The invention further consists in certain novel features of construction and arrangement of parts whichwill .be readily understood by reference to the description of the drawings and to the claims to be hereinafter given.

For the purpose of illustrating the invention, one preferred form thereof is illustrated in the drawings, this form having been found to give satisfactory and reliable results, although it is to be understood that I the invention is not limited to the precise arrangement and organization of these in strumentalities as herein shown and "described, except as required by the scope of the appended claims.

Of the drawings:

Figure 1 represents an elevation of a last embodying the principles of the present invention.

Fig. 2 represents a longitudinal vertical section of the same, and

Fig. 3 represents a" horizontal section of a portion of the same.

Similar characters indicate like parts throughout the several figures of the drawings.

In the drawings, 10 is the fore-part of a last and 11 is the heel-part thereof.

' The upper portion 12 of the rear face of the fore-part is inclined upwardly toward the toe and the upper portion 13 of the front face of the heel-part 11 is inclined in the opposite direction.

The lower portion of the adjacent faces of the fore-part 10 and heel-part 11 are normally in contact as indicated at 14 in Figs. 1 and 2 of the drawings.

The rear face of the fore-part 10 has a semi-cylindrical. transverse depression "15 therein and the front face of the heel-part 11 is provided with a similar transverse semi-cylindrical depression 16.

At the ends of the semi-cylindrical depressions 15, 16 are the larger semi-cylindrical depressions 17, 18 in the inner ends of which are positioned the metal rings 19, the inner diameter of which is the same as the diameter of the opening formed by the combined semi-cylindrical depressions 15, 1G.

Disposed in the semi-cylindrical depressions 17, are the cylindrical blocks 20 which are glued to the fore-part 10 and extend into the semi-cylindrical depressions 18.

These blocks 20 are also secured to the fore-part 10 by means of brads 21.

Each block 20 is provided with a centrally disposed cylindrical recess 22, in

alinernent with the cylindrical chamber formed by the depressions 15, 16.

Between the inner ends of the blocks 20, 22 extend the two segments 23 of the cylinder, each segment being provided with a cylindrical shank 23 driven into one of the parts 10, 11 of the last.

Each shank is provided with a hole therethrough through which a pin 24 is driven from the bottom of the last.

This in 24 prevents any outward movement 0' the segments 23 and retains them in their respective depressions 15, 16.

Each segment 23 is less than a half cylinder and the lower radial face of each segment is adapted to be alined with the faces 1410f the fore-part 10 and heel-part 11 of the last, as indicated in Fig. 2 of the drawlngs.

Above the axis 25 of the cylindrical segments 23 is a V-shaped space which permits the last to be broken by moving one part 10 or 11 of the last relatively to the other part thereof. 4 p

The outer ends of the segments 23 extend through the rings 19 which form a bearing for said segments when the'two parts of the last are moved relatively to each other. These rings 19, surrounding the ends pf the segments 23, prevent the separation of the two parts 10, 11 of the last while the end blocks 20 bearing against the ends of the segments 23 prevent either of said segments moving endwise relatively to the other.

The fore-part 10 has a hole 26 therein in which is positioned the pin 27 having a rounded head 28 forced against the inclined face 13 of the heel-part 11 by the helical spring 29'the opposite end of which is disposed in a depression 30 in the inclined face 12 of the fore-part 10. I

The spring 29 normally retains the two parts 10, 11 of the last in extended position but may. be compressed to permit the last to be broken.

No novelty exists in the means employed fordreeping the last extended under normal. conditions, the present invention consisting in the means employed for making a hinge connection between the two parts of the divided last.

This construction of hinge connection is inexpensive to make and is readily assembled to connect the two parts of the last.

It is so constructed that the wooden parts of the last do not require to be weakened by numerous slots and openings such as are usually required in order to install the hinge connections in general use.

It is believed that the operation and many advantages of the invention will be readily understood without further description.

Having thus described my invention, I claim:

1. In a last, a fore-part; a heel-part; segments of a cylinder secured to said parts with contacting faces below the axis of said cylinder and separated faces above said axis; and means preventing separation of said segments while permitting movement about said axis.

2. In a last, a fore-part; a heel-part; segments of a cylinder secured to said parts with contacting faces below the axis of said cylinder and separated faces above said axis; means preventing separation of said segments while permitting movement about said axis; and means secured to said forepart for preventing end movement of said segments relatively to each other.

3. In a last, a fore-part; a heel-part; ments of a cylinder secured to said parts with contacting faces below the axis of said cylinder and separated faces above said axis; and rings surrounding the outer ends of said se ments.

4. In a ast, a fore-part; a heel-part; and segments of a cylinder secured to said parts with contacting faces below and separated faces above the axis of said cylinder and having their outer ends positioned in circular depressions.

5. In a last, a fore-part; a heel-part; segments of a cylinder interposed between said parts with contacting faces below and separated faces above the axis of said cylinder; means preventing the separation of said segments while permitting one to oscillate relatively to the other; and a shank on each segment driven into one of said parts.

6. In a last, a fore-part; a heel-part; segments of a cylinder interposed between said parts with contacting faces below and sep arated faces above the axis of said cylinder; means preventing the separation of said segments while permitting one to oscillate relatively to the other; a shank on each segment driven into one of said parts; and a pin driven through an opening on each shank.

7. In a last, a fore-part; a heel-part; segments of a cylinder secured to said parts with contacting faces below and separated faces above the axis of said cylinder; rings surrounding the ends of said segments; and blocks secured to the fore-part beyondv the ends of said cylinder and abutting said rings.

8. In a last, a fore-part; a heel-part; segments of a cylinder secured to said parts with contacting faces below and separated faces above the axis of said cylinder; rings surrounding the ends of said segments; and blocks secured to the fore-part beyond the ends of said cylinder and abutting said rings said blocks having cylindrical recesses into which the ends of said segments extend. Y

9. In a last, a fore-part and a heel-part having semi-cylindrical transverse depressions in their adjacent faces with larger semi-cylindrical depressions at opposite ends thereof; rings in said larger depressions; and a cylinder segment secured to each part in said transverse depression with ends in said rings.

10. In a last, a fore-part and a heel-part having semi-cylindrical transverse depressions in their adjacent faces with larger semi-cylindrical depressions at opposite ends thereof; rings in said larger depressions; a cylinder segment secured to each part in said transverse depression with the ends in said rings; and closing blocks secured to one of said parts and fitted to said lar er depressions.
